+ * StaticComponent Interface
+ *
+ * For server-side rendered components without state management.
+ * Counterpart to LiveComponentContract for static HTML generation.
+ *
+ * Constructor Contract:
+ * - Components MUST accept: __construct(string $content, array $attributes = [])
+ * - $content: Inner HTML/text content from template
+ * - $attributes: Key-value pairs from template attributes
+ *
+ * Returns HTML Node Tree instead of strings for:
+ * - Type safety and validation
+ * - AST manipulation (CSP, sanitization, transformations)
+ * - Better testability
+ * - Consistency with DomTemplateParser
+ *
+ * Example Implementation:
+ * ```php
+ * #[ComponentName('button')]
+ * final readonly class Button implements StaticComponent
+ * {
+ *     private string $variant;
+ *     private string $content;
+ *
+ *     public function __construct(string $content, array $attributes = [])

+ *         return $button;

+ *
+ * Template Usage:
+ * ```html
+ * <x-button variant="primary">Click Me</x-button>

+                    <li>✅ <strong>Conditional Caching:</strong> `shouldCache()` controls caching per request</li>
+                    <li>✅ <strong>Manual Invalidation:</strong> Refresh action invalidates cache on demand</li>
+                    <li>✅ <strong>Performance Boost:</strong> 500x faster rendering with cache</li>
